In the title compound, C(19)H(20)O(2)S, the cyclo-hexyl ring adopts a chair conformation and the aryl-sulfinyl unit is positioned equatorial relative to the cyclo-hexyl group. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O hydrogen bonds. The O atom of the sulfinyl group is disordered over two orientations with site-occupancy factors of 0.923 (3) and 0.077 (3).

The title compound, C(14)H(21)NO(2)S, synthesized by N-methyl-ation of cyclo-hexyl-amine sulfonamide with ethyl iodide is of inter-est as a precursor to biologically active sulfur-containing heterocyclic compounds. There are two independent mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the phenyl ring and the cyclo-hexyl ring are 40.29 (11) and 37.91 (13)° in...

The complete mol-ecule of the title compound, C(19)H(34)N(2)S, is generated by crystallographic twofold symmetry, with the C=S group lying on the rotation axis. A short C-H⋯S contact occurs in the mol-ecule. The five-membered ring is twisted and the cyclo-hexyl ring adopts a chair conformation. The dihedral angle between the mean plane of the five-membered ring and the basal plane of the cyclo-...

The reaction of cyclo-hexyl isocyanide and alkyl-idene Meldrum's acid (systematic name 2,2-dimethyl-1,3-dioxane-4,6-dione) in the presence of cyclo-hexyl ketoxime and dichloro-methane as solvent resulted in the title compound, 2C(28)H(43)N(3)O(5)·H(2)O. One methyl-ene group of the cyclo-pentane ring was found to be disordered and was refined with occupancies 0.75:0.25. Intra-molecular N-H⋯O hyd...

In the title asymmetric di-cyclo-hexyl-phenyl-guanidine, C25H41N3, the central guanidine C atom deviates by only 0.004 (2) Å from the central plane defined by the three N atoms. The benzene and the cyclo-hexyl rings are rotated out of the central plane of the N3C unit by 85.63 (12)° (benzene) and 51.52 (9) and 49.37 (12)° (cyclohexyl). The crystal packing features only by van der Waals inter-ac...

The title compound, C(19)H(31)O(2)P, features a distorted tetra-hedral P atom that bonds to the phenyl ring, isopropyl and 2-isopropyl-5-methyl-cyclo-hexyl groups, and is determined as having an R(p) configuration. A chair conformation is observed for the cyclo-hexyl ring. In the crystal, mol-ecules are linked into chains running along the a axis by weak inter-molecular C-H⋯O hodrogen bonds.

The title compound, C(31)H(38)N(2), was prepared from bis-(4-amino-cyclo-hexyl)methane and two equivalents of cinnamaldehyde. The cyclo-hexyl groups each show a chair conformation and the α,β-unsaturated imine side chains are all-trans configured. Two mol-ecules of the title compound as well as two trichloromethane solvent mol-ecules are present in the asymmetric unit. The solvent mol-ecules in...

In the title compound, C22H32O4, the atoms of the methyl ester group and the alk-oxy O atoms are all coplanar with the central aromatic ring, with an r.m.s. deviation of 0.008 Å. Bonds to the methyl-ene and cyclo-hexyl groups are also very close to this plane, so that the mol-ecule is essentially flat, apart from the cyclo-hexyl groups. The mean planes through the cyclo-hexyl groups are tilted ...

In the title compound, C17H20ClN3OS, the mean plane of the central thio-urea core makes dihedral angles of 26.56 (9) and 47.62 (12)° with the mean planes of the chromene moiety and the cyclo-hexyl ring, respectively. The cyclo-hexyl ring adopts a chair conformation. The N-H atoms of the thio-urea unit adopt an anti conformation. The chromene group is positioned trans, whereas the cyclo-hexyl ri...

The title compound, C15H18N2O2S {systematic name: 6-[2-(cyclo-hexyl-sulfan-yl)eth-yl]-5H-pyrrolo-[3,4-b]pyridine-5,7(6H)-dione}, was obtained from the reaction of pyridine-2,3-di-carb-oxy-lic anhydride (synonym: quinolinic anhydride) with 2-(cyclo-hexyl-sulfan-yl)ethyl-amine. The dihedral angle between the mean plane of the cyclo-hexyl ring and the quinolinic acid imide ring is 25.43 (11)°. In ...
